Clean fuel use up 40%

Global revenues for solar photovoltaic products, wind power, biofuels, and fuel cells rose from $55 billion in 2006 to $77 billion in 2007. The biofuels industry produced 13 billion gallons of ethanol and 2 billion gallons of biodiesel; solar photovoltaic system installations fell just short of 3,000 MW. Visit www.cleanedge.com.

Attention, renewable-energy developers

As part of New York City's goal to shrink greenhouse gas emissions 30% by 2030, the Department of Administrative Services is seeking partners to buy, install, own, and maintain solar panels on 11 city-owned buildings in all five boroughs. The effort to double the city's solar electric capacity to 2 MW is made possible by the U.S. Department of Energy, which designated New York a “Solar America” city last year.
